[Qgis-user] Icons of GRASS tool do not display

[Patrick Giraudoux]

Dear listers,

I have just installed QGIS Lyon with GRASS 6.4.4 (standalone), on 
Windows 7,  but cannot get the usual GRASS toolbar (I just have "open 
the GRASS tools" and "set de current region" icons. This makes me unable 
to display GRASS rasters or vectors into QGIS. However, in earlier 
projects where GRASS objects were already displayed in QGIS, I get them 
displayed OK as layers...


Any idea about how to proceed to get access to the commands "Add a 
raster layer from GRASS" or "Add a vector layer from GRASS"?


Best,

Patrick

Re: [Qgis-user] Geoserver WFS update request error

[Richard Duivenvoorde]

Hi Maxx,

a very thourough bug report!

plz create an issue for it. It would even be better if you had a public
wfs while this issue is not fixed...

Looking into http://www.w3.org/TR/1999/REC-xml-names-19990114/#dt-NSDecl
to me it looks like you should use the namespace prefix in the xmlns
attributes, not the uri's. So that would make QGIS generate not 100%
valid xml? But I'm not a xml gury myself.

https://github.com/qgis/QGIS/blob/master/src/providers/wfs/qgswfsprovider.cpp#L53

is the place where you see the declaration of the namespace part of the
elements when building the xml:

https://github.com/qgis/QGIS/blob/master/src/providers/wfs/qgswfsprovider.cpp#L496

2 options:
- xml guru confirms that it is not ok to write a uri in a xmlns attribute
- if you are able to compile yourself, you could try to change #53 to
change to 'wfs' instead of the uri, and check if all requests are still
valid...

Hope this helps, others please chime in

Regards,

Richard

Sorry to respond to myself, but I have found a solution, and I thought 
it may help other users. There are no longer icons to display GRASS 
raster/vector objects in a tool bar, but the user must use the QGIS 
browser panel ("explorateur" in French) to fetch the appropriate file in 
the relevant GRASS project (see 
https://www.qgis.org/fr/site/forusers/visualchangelog212/index.html#plugins).


Must admit I prefer the straight solution of earlier versions, where a 
dialog box permitted easy access to the GRASS mapset that was opened 
from icons. Anyway, no choice in the latest version as long as I 
understand... Suppose there has been good reasons to do so and that I 
will discover them later :-)

Re: [Qgis-user] QGIS 2.8.1 launch aborts with core dumped

[Blumentrath, Stefan]

Hi,


I am facing a similar issue with the other QGIS Versions on the same OS.


I suspect it is a kernel issue. Did you install latest Ubuntu kernel? That 
hopefully fixes the issue (I am testing at the moment...).


Cheers

Stefan

Try erase or rename your .qgis2 folder.

So far I
purged qgis, removed all qgis plugins
re installed using repository

but without any success

on another machine with similar OS and QGIS there are no such problems.

any ideas?

[Qgis-user] wfs server and filter parameter

[Jachym Cepicky]

Hi,
I would like to get QGIS WFS server up and running using FILTER option. I'm
working with OWSLib for the query generation, which I have tested on
various other WFS-server implementations and it always worked.

Do I see correctly, that WFS produced by QGIS supports

...







...

between and like operators?

Any hint, why this url (note the FILTER parameter)

http://localhost/cgi-bin/qgis_mapserv.fcgi?MAP=/var/www/html/tmp/natural-earth/central-europe.qgs=GeoJSON=WFS=*=GetFeature=http://www.opengis.net/ogc
">NAMEPrague=Places=1.0.0

returns no features (the response GeoJSON is formated well though)?

Thanks

Jachym

Re: [Qgis-user] Icons of GRASS tool do not display

[Terry Morse]

I agree. The toolbar takes up the same amount of screen space whether it has 
two icons or a dozen. The GRASS tools sidebar takes additional space. This 
seems unnecessary. Unless there is some compelling reason for doing it the new 
way, I hope it will revert to the old way in the next version.
